4 * added support for SHA-256 as X.509 certificate digest when using the
5 internal X.509/TLSv1 implementation
6 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
8 * fixed internal TLSv1 implementation for abbreviated handshake (used
10 * added support for setting VLAN ID for STAs based on local MAC ACL
11 (accept_mac_file) as an alternative for RADIUS server-based
13 * updated management frame protection to use IEEE 802.11w/D6.0
14 (adds a new association ping to protect against unauthenticated
15 authenticate or (re)associate request frames dropping association)
16 * added support for using SHA256-based stronger key derivation for WPA2
20 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
21 Identity Request if identity is already known
22 * added support for EAP Sequences in EAP-FAST Phase 2
23 * added support for EAP-TNC (Trusted Network Connect)
24 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
25 changes needed to run two methods in sequence (IF-T) and the IF-IMV
26 and IF-TNCCS interfaces from TNCS)
27 * added support for optional cryptobinding with PEAPv0
28 * added fragmentation support for EAP-TNC
29 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
31 * added support for opportunistic key caching (OKC)
34 * fixed Reassociation Response callback processing when using internal
35 MLME (driver_{hostap,nl80211,test}.c)
36 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
37 * copy optional Proxy-State attributes into RADIUS response when acting
38 as a RADIUS authentication server
39 * fixed EAPOL state machine to handle a case in which no response is
40 received from the RADIUS authentication server; previous version
41 could have triggered a crash in some cases after a timeout
42 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to
44 * added a workaround for EAP-SIM/AKA peers that include incorrect null
45 termination in the username
46 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
47 attribute in notification messages only when using fast
49 * fixed EAP-SIM Start response processing for fast reauthentication
51 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
52 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
55 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
56 lengths properly to avoid potential crash caused by invalid messages
57 * added data structure for storing allocated buffers (struct wpabuf);
58 this does not affect hostapd usage, but many of the APIs changed
59 and various interfaces (e.g., EAP) is not compatible with old
61 * added support for protecting EAP-AKA/Identity messages with
62 AT_CHECKCODE (optional feature in RFC 4187)
63 * added support for protected result indication with AT_RESULT_IND for
64 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
65 * added support for configuring EAP-TTLS phase 2 non-EAP methods in
66 EAP server configuration; previously all four were enabled for every
67 phase 2 user, now all four are disabled by default and need to be
68 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
70 * removed old debug printing mechanism and the related 'debug'
71 parameter in the configuration file; debug verbosity is now set with
72 -d (or -dd) command line arguments
73 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
74 only shared key/password authentication is supported in this version
77 * added experimental, integrated TLSv1 server implementation with the
78 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
79 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
80 .config); this can be useful, e.g., if the target system does not
81 have a suitable TLS library and a minimal code size is required
82 * added support for EAP-FAST server method to the integrated EAP
84 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
85 draft (draft-ietf-emu-eap-gpsk-07.txt)
86 * added a new configuration parameter, rsn_pairwise, to allow different
87 pairwise cipher suites to be enabled for WPA and RSN/WPA2
88 (note: if wpa_pairwise differs from rsn_pairwise, the driver will
89 either need to support this or will have to use the WPA/RSN IEs from
90 hostapd; currently, the included madwifi and bsd driver interfaces do
91 not have support for this)
92 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
95 * added experimental IEEE 802.11r/D6.0 support
96 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
97 * updated EAP-PSK to use the IANA-allocated EAP type 47
98 * fixed EAP-PSK bit ordering of the Flags field
99 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
100 by reading wpa_psk_file [Bug 181]
101 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
102 * fixed IPv6 connection to RADIUS accounting server
103 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
104 draft (draft-ietf-emu-eap-gpsk-04.txt)
105 * hlr_auc_gw: read GSM triplet file into memory and rotate through the
106 entries instead of only using the same three triplets every time
107 (this does not work properly with tests using multiple clients, but
108 provides bit better triplet data for testing a single client; anyway,
109 if a better quality triplets are needed, GSM-Milenage should be used
110 instead of hardcoded triplet file)
111 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
112 in Success Request [Bug 203]
113 * added support for sending EAP-AKA Notifications in error cases
114 * updated to use IEEE 802.11w/D2.0 for management frame protection
116 * RADIUS server: added support for processing duplicate messages
117 (retransmissions from RADIUS client) by replying with the previous
121 * added support for configuring and controlling multiple BSSes per
122 radio interface (bss=<ifname> in hostapd.conf); this is only
123 available with Devicescape and test driver interfaces
124 * fixed PMKSA cache update in the end of successful RSN
126 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
127 for each STA based on RADIUS Access-Accept attributes); this requires
128 VLAN support from the kernel driver/802.11 stack and this is
129 currently only available with Devicescape and test driver interfaces
130 * driver_madwifi: fixed configuration of unencrypted modes (plaintext
131 and IEEE 802.1X without WEP)
132 * removed STAKey handshake since PeerKey handshake has replaced it in
133 IEEE 802.11ma and there are no known deployments of STAKey
134 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
135 draft (draft-ietf-emu-eap-gpsk-01.txt)
136 * added preliminary implementation of IEEE 802.11w/D1.0 (management
138 (Note: this requires driver support to work properly.)
139 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
140 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
141 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
142 parameters from a text file to make it possible to implement proper
143 GSM/UMTS authentication server for multiple SIM/USIM cards using
145 * fixed session timeout processing with drivers that do not use
146 ieee802_11.c (e.g., madwifi)
149 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
150 hostapd (e.g., to initialize wired network authentication based on an
152 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
153 using WPA2 even if PMKSA caching is not used
154 * added -P<pid file> argument for hostapd to write the current process
156 * added support for RADIUS Authentication Server MIB (RFC 2619)
159 * fixed nt_password_hash build [Bug 144]
160 * added PeerKey handshake implementation for IEEE 802.11e
161 direct link setup (DLS) to replace STAKey handshake
162 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
163 draft-clancy-emu-eap-shared-secret-00.txt)
164 * fixed a segmentation fault when RSN pre-authentication was completed
165 successfully [Bug 152]
168 * do not build nt_password_hash and hlr_auc_gw by default to avoid
169 requiring a TLS library for a successful build; these programs can be
170 build with 'make nt_password_hash' and 'make hlr_auc_gw'
171 * added a new configuration option, eapol_version, that can be used to
172 set EAPOL version to 1 (default is 2) to work around broken client
173 implementations that drop EAPOL frames which use version number 2
175 * added support for EAP-SAKE (no EAP method number allocated yet, so
176 this is using the same experimental type 255 as EAP-PSK)
177 * fixed EAP-MSCHAPv2 message length validation
180 * fixed stdarg use in hostapd_logger(): if both stdout and syslog
181 logging was enabled, hostapd could trigger a segmentation fault in
182 vsyslog on some CPU -- C library combinations
183 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
184 program to make it easier to use for implementing real SS7 gateway;
185 eap_sim_db is not anymore used as a file name for GSM authentication
186 triplets; instead, it is path to UNIX domain socket that will be used
187 to communicate with the external gateway program (e.g., hlr_auc_gw)
188 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
189 local information (GSM authentication triplets from a text file and
190 hardcoded AKA authentication data); this can be used to test EAP-SIM
192 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
193 to make it possible to test EAP-AKA with real USIM cards (this is
194 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
196 * driver_madwifi: added support for getting station RSN IE from
197 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
198 broken with earlier change (r1357) in the driver
199 * changed EAP method registration to use a dynamic list of methods
200 instead of a static list generated at build time
201 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
203 * added ap_max_inactivity configuration parameter
206 * driver_test: added better support for multiple APs and STAs by using
207 a directory with sockets that include MAC address for each device in
208 the name (test_socket=DIR:/tmp/test)
209 * added support for EAP expanded type (vendor specific EAP methods)
211 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
212 * added experimental STAKey handshake implementation for IEEE 802.11e
213 direct link setup (DLS); note: this is disabled by default in both
214 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
216 * added support for EAP methods to use callbacks to external programs
217 by buffering a pending request and processing it after the EAP method
219 * improved EAP-SIM database interface to allow external request to GSM
220 HLR/AuC without blocking hostapd process
221 * added support for using EAP-SIM pseudonyms and fast re-authentication
222 * added support for EAP-AKA in the integrated EAP authenticator
223 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
224 user database to allow EAP-SIM/AKA selection without extra roundtrip
225 for EAP-Nak negotiation
226 * added support for storing EAP user password as NtPasswordHash instead
227 of plaintext password when using MSCHAP or MSCHAPv2 for
228 authentication (hash:<16-octet hex value>); added nt_password_hash
229 tool for hashing password to generate NtPasswordHash
231 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
232 * driver_wired: fixed EAPOL sending to optionally use PAE group address
233 as the destination instead of supplicant MAC address; this is
234 disabled by default, but should be enabled with use_pae_group_addr=1
235 in configuration file if the wired interface is used by only one
236 device at the time (common switch configuration)
237 * driver_madwifi: configure driver to use TKIP countermeasures in order
238 to get correct behavior (IEEE 802.11 association failing; previously,
239 association succeeded, but hostpad forced disassociation immediately)
240 * driver_madwifi: added support for madwifi-ng
243 * added support for replacing user identity from EAP with RADIUS
244 User-Name attribute from Access-Accept message, if that is included,
245 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
246 tunneled identity into accounting messages when the RADIUS server
247 does not support better way of doing this with Class attribute)
248 * driver_madwifi: fixed EAPOL packet receive for configuration where
249 ath# is part of a bridge interface
250 * added a configuration file and log analyzer script for logwatch
251 * fixed EAPOL state machine step function to process all state
252 transitions before processing new events; this resolves a race
253 condition in which EAPOL-Start message could trigger hostapd to send
254 two EAP-Response/Identity frames to the authentication server
257 * added client CA list to the TLS certificate request in order to make
258 it easier for the client to select which certificate to use
259 * added experimental support for EAP-PSK
260 * added support for WE-19 (hostap, madwifi)
263 * fixed build without CONFIG_RSN_PREAUTH
264 * fixed FreeBSD build
267 * fixed PMKSA caching to copy User-Name and Class attributes so that
268 RADIUS accounting gets correct information
269 * start RADIUS accounting only after successful completion of WPA
270 4-Way Handshake if WPA-PSK is used
271 * fixed PMKSA caching for the case where STA (re)associates without
275 * EAP-PAX is now registered as EAP type 46
276 * fixed EAP-PAX MAC calculation
277 * fixed EAP-PAX CK and ICK key derivation
278 * renamed eap_authenticator configuration variable to eap_server to
279 better match with RFC 3748 (EAP) terminology
280 * driver_test: added support for testing hostapd with wpa_supplicant
281 by using test driver interface without any kernel drivers or network
285 * fixed RADIUS server initialization when only auth or acct server
286 is configured and the other one is left empty
287 * driver_madwifi: added support for RADIUS accounting
288 * driver_madwifi: added preliminary support for compiling against 'BSD'
289 branch of madwifi CVS tree
290 * driver_madwifi: fixed pairwise key removal to allow WPA reauth
291 without disassociation
292 * added support for reading additional certificates from PKCS#12 files
293 and adding them to the certificate chain
294 * fixed RADIUS Class attribute processing to only use Access-Accept
295 packets to update Class; previously, other RADIUS authentication
296 packets could have cleared Class attribute
297 * added support for more than one Class attribute in RADIUS packets
298 * added support for verifying certificate revocation list (CRL) when
299 using integrated EAP authenticator for EAP-TLS; new hostapd.conf
300 options 'check_crl'; CRL must be included in the ca_cert file for now
302 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
303 * added support for including network information into
304 EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
305 (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
306 * fixed a bug which caused some RSN pre-authentication cases to use
307 freed memory and potentially crash hostapd
308 * fixed private key loading for cases where passphrase is not set
309 * added support for sending TLS alerts and aborting authentication
310 when receiving a TLS alert
311 * fixed WPA2 to add PMKSA cache entry when using integrated EAP
313 * fixed PMKSA caching (EAP authentication was not skipped correctly
314 with the new state machine changes from IEEE 802.1X draft)
315 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
316 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
317 to be added to .config to include IPv6 support); for RADIUS server,
318 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
319 in RADIUS clients file can then use IPv6 format
320 * added experimental support for EAP-PAX
321 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
322 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
324 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
327 * added support for configuring a forced PEAP version based on the
329 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
330 to terminate authentication
331 * fixed EAP identifier duplicate processing with the new IEEE 802.1X
333 * clear accounting data in the driver when starting a new accounting
335 * driver_madwifi: filter wireless events based on ifindex to allow more
336 than one network interface to be used
337 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
338 setting if the packet does not pass MIC verification (e.g., due to
339 incorrect PSK); previously, message 1/4 was not tried again if an
340 invalid message 2/4 was received
341 * fixed reconfiguration of RADIUS client retransmission timer when
342 adding a new message to the pending list; previously, timer was not
343 updated at this point and if there was a pending message with long
344 time for the next retry, the new message needed to wait that long for
348 * added support for configuring multiple allowed EAP types for Phase 2
349 authentication (EAP-PEAP, EAP-TTLS)
350 * fixed EAPOL-Start processing to trigger WPA reauthentication
351 (previously, only EAPOL authentication was done)
354 * added support for EAP-PEAP in the integrated EAP authenticator
355 * added support for EAP-GTC in the integrated EAP authenticator
356 * added support for configuring list of EAP methods for Phase 1 so that
357 the integrated EAP authenticator can, e.g., use the wildcard entry
358 for EAP-TLS and EAP-PEAP
359 * added support for EAP-TTLS in the integrated EAP authenticator
360 * added support for EAP-SIM in the integrated EAP authenticator
361 * added support for using hostapd as a RADIUS authentication server
362 with the integrated EAP authenticator taking care of EAP
363 authentication (new hostapd.conf options: radius_server_clients and
364 radius_server_auth_port); this is not included in default build; use
365 CONFIG_RADIUS_SERVER=y in .config to include
368 * removed 'daemonize' configuration file option since it has not really
369 been used at all for more than year
370 * driver_madwifi: fixed group key setup and added get_ssid method
371 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
374 * added support for integrated EAP-TLS authentication (new hostapd.conf
375 variables: ca_cert, server_cert, private_key, private_key_passwd);
376 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
377 external RADIUS server
378 * added support for reading PKCS#12 (PFX) files (as a replacement for
379 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
381 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
382 * added support for Acct-{Input,Output}-Gigawords
383 * added support for Event-Timestamp (in RADIUS Accounting-Requests)
384 * added support for RADIUS Authentication Client MIB (RFC2618)
385 * added support for RADIUS Accounting Client MIB (RFC2620)
386 * made EAP re-authentication period configurable (eap_reauth_period)
387 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
388 * fixed EAPOL state machine to stop if STA is removed during
389 eapol_sm_step(); this fixes at least one segfault triggering bug with
390 IEEE 802.11i pre-authentication
391 * added support for multiple WPA pre-shared keys (e.g., one for each
392 client MAC address or keys shared by a group of clients);
393 new hostapd.conf field wpa_psk_file for setting path to a text file
394 containing PSKs, see hostapd.wpa_psk for an example
395 * added support for multiple driver interfaces to allow hostapd to be
396 used with other drivers
397 * added wired authenticator driver interface (driver=wired in
398 hostapd.conf, see wired.conf for example configuration)
399 * added madwifi driver interface (driver=madwifi in hostapd.conf, see
400 madwifi.conf for example configuration; Note: include files from
401 madwifi project is needed for building and a configuration file,
402 .config, needs to be created in hostapd directory with
403 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
405 * fixed an alignment issue that could cause SHA-1 to fail on some
406 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
408 * fixed RADIUS reconnection after an error in sending interim
410 * added hostapd control interface for external programs and an example
411 CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
412 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
413 'hostapd_cli sta <addr>')
414 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
415 * added support for strict GTK rekeying (wpa_strict_rekey in
417 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
418 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
420 * added Prism54 driver interface (driver=prism54 in hostapd.conf;
421 note: .config needs to be created in hostapd directory with
422 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
424 * dual-licensed hostapd (GPLv2 and BSD licenses)
425 * fixed RADIUS accounting to generate a new session id for cases where
426 a station reassociates without first being complete deauthenticated
427 * fixed STA disassociation handler to mark next timeout state to
428 deauthenticate the station, i.e., skip long wait for inactivity poll
429 and extra disassociation, if the STA disassociates without
431 * added integrated EAP authenticator that can be used instead of
432 external RADIUS authentication server; currently, only EAP-MD5 is
433 supported, so this cannot yet be used for key distribution; the EAP
434 method interface is generic, though, so adding new EAP methods should
435 be straightforward; new hostapd.conf variables: 'eap_authenticator'
436 and 'eap_user_file'; this obsoletes "minimal authentication server"
437 ('minimal_eap' in hostapd.conf) which is now removed
438 * added support for FreeBSD and driver interface for the BSD net80211
439 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
440 .config); please note that some of the required kernel mods have not
443 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
444 * fixed some accounting cases where Accounting-Start was sent when
445 IEEE 802.1X port was being deauthorized
448 * modified RADIUS client to re-connect the socket in case of certain
449 error codes that are generated when a network interface state is
450 changes (e.g., when IP address changes or the interface is set UP)
451 * fixed couple of cases where EAPOL state for a station was freed
452 twice causing a segfault for hostapd
453 * fixed couple of bugs in processing WPA deauthentication (freed data
457 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
458 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
459 cases where STAs dropped multicast frames as replay attacks
460 * added support for copying RADIUS Attribute 'Class' from
461 authentication messages into accounting messages
462 * send canned EAP failure if RADIUS server sends Access-Reject without
463 EAP message (previously, Supplicant was not notified in this case)
464 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
465 not start EAPOL state machines if the STA selected to use WPA-PSK)
468 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
469 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
470 (i.e., IEEE 802.11i/D3.0)
471 - supports WPA-only, RSN-only, and mixed WPA/RSN mode
472 - both WPA-PSK and WPA-RADIUS/EAP are supported
473 - PMKSA caching and pre-authentication
474 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
475 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
476 rsn_preauth, rsn_preauth_interfaces
477 * fixed interim accounting to remove any pending accounting messages
478 to the STA before sending a new one
481 * added support for Acct-Interim-Interval:
482 - draft-ietf-radius-acct-interim-01.txt
483 - use Acct-Interim-Interval attribute from Access-Accept if local
484 'radius_acct_interim_interval' is not set
485 - allow different update intervals for each STA
486 * fixed event loop to call signal handlers only after returning from
487 the real signal handler
488 * reset sta->timeout_next after successful association to make sure
489 that the previously registered inactivity timer will not remove the
490 STA immediately (e.g., if STA deauthenticates and re-associates
491 before the timer is triggered).
492 * added new hostapd.conf variable, nas_identifier, that can be used to
493 add an optional RADIUS Attribute, NAS-Identifier, into authentication
494 and accounting messages
495 * added support for Accounting-On and Accounting-Off messages
496 * fixed accounting session handling to send Accounting-Start only once
497 per session and not to send Accounting-Stop if the session was not
499 * fixed Accounting-Stop statistics in cases where the message was
500 previously sent after the kernel entry for the STA (and/or IEEE
501 802.1X data) was removed
506 Older changes up to and including v0.1.0 are included in the ChangeLog
507 of the Host AP driver.
